However, there is still room for improvement. Even if you only drink plant-based milk, the amount of greenhouse gas emissions fluctuates significantly. While rice milk is known to have the highest impact on the planet (0.23kg per serving), almond milk has the lowest (0.14kg per serving). In comparison, traditional dairy milk produces 0.63kg of greenhouse gas emissions per serving (Stylianou, Guibourg, & Briggs, 2019). • Almond Milk: 0,14 • Rice Milk: 0,23 • Dairy Milk: 0,63 All this has led me to do more research on different products and their impact on the environment. While trying my best to stay away from different brands after reading an article about one or two companies who claim to be sustainable but are not, I also came across the petition of OATLY, which wants to introduce a CO2 label on foods. The goal of the petition was that food manufacturers should include CO2 emissions on each food they supply. By CO2 emissions, they mainly refer to CO2 but also other equivalent greenhouse gas emissions like methane). OATLY itself already voluntarily put their CO2 emissions on their milk packaging to help customers make responsible and self-aware choices. This is where the idea of reduco2 started to form itself. What if there is an app, which is similar to most other food tracking apps I love to use (such as “Life sum” and “Myfitnesspal”) but does not focus on nutrients but the greenhouse gas emissions one ultimately is responsible for when buying the product? By simply implementing a carbon label onto every food, consumers will be able to make reasonable and, hopefully, more sustainable choices. By creating a user-friendly application to help the consumer keeping on track with the individual impact on the environment through educational techniques, we can promote an increasing awareness and aim to collectively get out of the crisis that we are facing today. 22
